A phone app could be handy for a couple of things.
  1. Take photos of receipts in app and match them to bank transaction as they occur. I already do this in a very round about way that is time consuming and involves saving each photo to my phone.
  2. GST coding i.e. when have a spare 5 minutes waiting for an appointment.
  3. A read only option to view budgets and extended codes. i.e. when in meetings with accountant and bank manager.
  4. I'm sure there are more!
